Blacks and whites basically dressed the same, gave their kids the same normal names, struggled to earn a living in the same ways in the jobs in the same factories.
In fact, blacks had an even higher rate of marriage and lower rate of illegitimate births than whites.
But in the last 50 years liberals have convinced blacks that everything in their lives happens, or doesn't happen because of their skin color and the racism of whites, bot only whites who aren't democrats.
This has led to blacks gradually departing from mainstream culture and developing their alternate culture where people call themselves African-American, speak differently, have low marriage rates but high out of wedlock birth rates, where women have 6 or 10 kids by different sperm donors all living on government handouts, where they give their children the most horrible, made up "black" names and where they ridicule other blacks for "acting white".
But the most important change has been the liberals success in convincing a large majority of blacks that the most significant aspect of their existence is their black skin. And that because of their black skin they are being victimized by whites and society in general.
Now we have a huge black population that is obsessed with skin color and think of themselves as "black" above all else. They have almost become a separate nation within America. They see their lives as a constant battle and struggle because of their skin color.
In general a white person will almost never think of their skin color when asked "who are you?" - They identify themselves as an American, a mother, a father, a homemaker, a Baptist, a Marine, a truckdriver, an enginerr, a doctor, etc.
But, thanks to fifty years of liberal brainwashing most blacks are obsessed with the color of their skins and place that at the top of the list when they self identify.
